对美国由次贷危机引起的金融风暴进行了研究，分别建立了次贷危机产生机理的模型和金融风暴的判定模型，并用计算机对模型进行了仿真。通过仿真分析得出了利率和房价的变动是形成次贷危机的直接原因，而信心指数却是形成危机的根本原因的结论。况，实现城市平面十字路口的微观仿真，通过仿真得到信号灯的最佳控制方式与这一控制方式下的交通拥堵情况。然后在取消左转的条件下从路网的角度分析道路交通流，通过对路网模型的分析，针对其较大的复杂度和边界缺陷，我们建立了其等效模型。改变进入系统的车流的性质仍然在单个十字路口建立模型进行仿真。经过两个模型的对比，我们得出“取消左转”这一方式有利于改善道路交通拥堵问题。最后提出其他可行的“无左转”交通流组织形式，并进行简单分析。(Subprime mortgage crisis matlab simulation)
